SOLUTION: In partition wall mounting structure for making fire resistance coating precede and a construction method, the web outer surface of a runner 3 is lap-welded to the web inner surface of a channel steel 2, and a special runner 1 with grooves M formed between the flanges of the channel steel 2 and the flanges of the runner 3 is installed at a steel frame. A partition wall is mounted after spraying fire resistant coating material 6 previously to the steel frame or a deck plate 5 including the outer peripheral part of the special runner 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a partition wall and a method for installing the same.

[0002]

2. Description of the Related Art Conventionally, fireproofing work was performed after completion of partitioning wall work, so there was no flexibility in the process, and fireproofing work was performed in a narrow space partitioned by partitioning walls. It was bad. Further, it has been difficult to accurately apply the thickness of the fireproof coating on the ceiling portion and to inspect the thickness. Therefore, there is a problem that the thickness of the refractory coating is excessively increased to be uneconomical, or that the thickness is insufficient to deteriorate the quality of the construction.

In order to solve the above problems, a runner made of grooved steel for the construction of a partition wall is first installed on a steel frame, a fireproof coating is applied to a steel frame portion and the like, and then a fireproof partition board (hereinafter referred to as a fireproof board). .) Mounting method is performed. However, this method has the following problems. When installing the fire-resistant board, it takes time to work such as removing the fire-resistant coating on the obstructive part or attaching the fire-resistant board to the uneven coating surface. The fire-resistant coating is peeled off, or a gap is formed between the fire-resistant coating and the fire-resistant board, and when the fire-resistant board is attached, repair such as spraying of fire-resistant material and ironing is required. Temporary scaffolding for post-construction work is required for repair. Despite the progress of other works, such as finishing work, the site is contaminated.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a rational and economical partition wall mounting structure and a method for constructing the partition wall, in which a fireproof coating work can be performed in advance. The purpose is to.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a mounting structure of a partition wall and a method of installing the partition wall in advance of a refractory coating, wherein the outer surface of a runner web is overlapped and welded to the inner surface of a channel steel web. A special runner with a groove formed between the flange of the mold steel and the flange of the runner is installed on the steel frame or deck plate, and after spraying the fire-resistant coating material on the steel frame or deck plate including the outer periphery of the special runner in advance, the partition wall And a method of installing the partition wall.

Embodiments of the present invention will be described below with reference to the drawings.

[0007]

FIG. 1 is a perspective view of a special runner 1 used in the present invention. In order to attach the vertical members (studs) constituting the framework of the lightweight steel frame partition, horizontal members (runners) are usually installed at the upper and lower ends of the wall. The special runner 1 used in the present invention overlaps and welds the web outer surface of the normally used runner 3 to the web inner surface of the channel steel 2 to form a groove M between the flange of the channel steel 2 and the flange of the runner 3. I have. In the groove M, a fireproof board 8 to be described later is fitted.

[0008]

The operation of the present invention will be described below.

<A> Installation of special runner FIG. 2 shows a deck plate 5 on which floor concrete 4 is cast.
FIG. 3 is a sectional view showing a state where a special runner 1 is installed by welding or the like. In the present embodiment, the special runner 1 is installed on the deck plate 5, but there is also a mode in which the special runner 1 is installed on a girder, a beam, or the like depending on the structural form, and studs forming a partitioning frame are attached.

<B> Construction of fireproof coating material After the special runner 1 is installed, the fireproof coating material 6 is sprayed on the steel frame or the deck plate 5 including the outer peripheral portion of the special runner 1. The refractory coating material 6 is sprayed by a known spraying machine 7.
Outer side surface of special runner 1 (flange 2a of channel steel 2,
(Required fireproof coating). The refractory covering material 6 that has entered the groove M into which the refractory board 8 is fitted is removed with a broom or the like after spraying.

<C> Start of Partition Wall Construction FIG. 3 is a cross-sectional view showing a state where two fireproof boards 8 are installed. According to the conventional method, the partition wall construction was performed in advance, and then the spraying of the refractory coating material 6 was performed. However, since the partition wall construction was performed in advance, the work efficiency was poor due to fireproof covering work in a narrow space partitioned by the partition wall. Flange 2 of channel steel 2
(a) Two refractory boards 8 are installed in grooves formed inside the runner 3 and outside the runner 3, and studs are attached to the partition space S formed between 8 and 8 to perform partition wall construction. For this reason, the degree of freedom in the process is increased and the work can be performed efficiently as compared with the conventional method in which the fireproof covering work is performed after the completion of the partition wall work.

[0012]

Since the present invention has been described above,
The following effects can be obtained. <B> Since the fireproof coating work was performed in advance,
Partition wall construction can be performed at any time, and the degree of freedom in the process is increased, and efficient work can be performed. <B> Since the refractory coating work is completed in advance, there is no need to rework the refractory coating, so that the inside of the post-construction site is not polluted and a comfortable working environment can be provided. <C> Since the fire-resistant coating of the steel frame is provided along the outer side surface (height) of the special runner, the gauge becomes a gauge for visually checking the thickness of the fire-resistant coating.
